If you have a virtual machine running in Oracle VirtualBox that you want to convert to run\import in Microsoft Hyper-V, then it's an easy process to convert a VDI virtual disk file to a VHDX file using a free tool called QEMU disk image utility.
Here is the sample command from the video.
qemu-img.exe convert -p "D:\VirtualBox VMs\Windows 11 Pro\Windows 11 Pro.vdi" -O vhdx "D:\VirtualBox VMs\Windows 11 Pro\Windows 11 Pro.vhdx"
Here is a link to download the free QEMU disk imaging software.
